Scaredy Cat

Well, we picked up little Sir William last night and brought him home. He's been very quiet, hardly said a word. We had one of the spare bedrooms set up as his 'transitional room'. Yesterday I rented a carpet cleaner and did all the upstairs floors. Plus we had gone through a lot of stuff up there in pitch/pack/giveaway mode, both in preparation for Willy the Wonder Cat and for eventually moving.
We did some shopping yesterday for the little guy: food dish, litter box, catnip, feathery-thing-on-a-stick, water dish (electric, recirculating, dome gizmo). He came with his own bed, some toys, food, and a carpet covered furniture/climby thing.
He spend most of last night scared. I sat in the room for a couple of hours until he finally poked his head out of the carrier. After very cautiously surveying the room, he hid under my chair. Eventually, I left the room to give him a chance to check things out privately. I went downstairs to watch a little TV. Soon came the thumping sounds of cat playing. Later, when I checked on him, he had eaten, used the litter, and played with one of his toy mice, but was back hiding. We checked on him a couple of times more last night and left the blinds open for some light.
Today he's still nervous. Spousal unit is sitting in there with him now. Given time I'm sure he'll adapt. We may wait up to a week before introducing him to Mowgli.
Mo is very curious about who's in that room, but she does not seem upset. A good sign, I think.
